Prostate MRI technical parameters standardization: A systematic review on adherence to PI-RADSv2 acquisition protocol

Highlights: • PI-RADS specifies acquisition parameters for optimal image interpretation. • Heterogenous reporting and overall adherence to protocol requirements was found. • Acquisition protocols were not significantly influenced by the PI-RADS revision. • Future PI-RADS revisions might benefit from streamlined protocol requirements. - Abstract: Purpose: The Prostate Imaging-Reporting and Data System has been developed to standardize prostate MRI in terms of acquisition, interpretation and reporting. It received a major revision in late 2014 (PI-RADSv2). Recently, doubts have been raised on imaging facilities adherence to its acquisition protocol. With this systematic review, we assessed adherence to PI-RADSv2 minimum technical specifications in literature, to achieve a better understanding of issues limiting their diffusion.
